Asked about Ten Hag's post-match response, Keane replied: "Listen, obviously he's had a couple of glasses of wine after the game. I don't know how strong that is, but he seemed really upbeat, and I admire him for it, because he's obviously seeing something that I'm not seeing at this moment in time.
"I'm not saying there's not potential at the football club or with these young players, but in terms of competing with Arsenal or Man City and Liverpool, they're way off it. They are competing at this moment in time with Aston Villa and Spurs for that fourth and fifth position, and at this stage, they're well behind them.
"So I don't get his positivity, but maybe that's just me obviously being a bit old and grumpy. He's upbeat, but I certainly didn't see that upbeat performance - I thought [there were] two very good goals from Man United and a team that hung in there and stuck at it, and I give them credit for that, but if you're looking at the bigger picture I'm not sitting back here and going 'Man United are on their way back'."
